He bowed and smiled. “That’s only natural and to be expected,” he said. “But this is what I came to talk to you about.” He paused a moment as though to collect his ideas, and then continued quickly: “You have, I believe, spent the last two months searching for your sister. I believe that, to a certain extent, I can help you in this search, or, rather, that I can put you in the way of helping yourself—seeking at a greater advantage and perhaps to better purpose. If you care to listen to me, I will tell you what I have in mind. But before doing so, I am forced to ask you for a pledge of absolute secrecy. That is quite essential.”
He waited then, and I stared at him in growing amazement. Of all the queer rigmarole——
He saw my expression and smiled. “Sounds like something straight out of a melodrama, doesn’t it?” he said. Then the smile left his face and he went on soberly: “Nevertheless, I am very much in earnest. I was never more serious in my life than I am now, in assuring you that I believe I can help you and that the pledge of secrecy is quite essential. You will see why at once, if you give it. As you know nothing at all about me, I might add that such a pledge will bind you to nothing at all dishonorable, nor will it force you to connive at anything dishonorable by your silence.”
“Good Lord, man,” I broke out at this, “what kind of a bee have you got in your bonnet? You seem to be in earnest, but what’s all this talk about secrecy? If you know anything about my sister, for God’s sake tell it to me and have done. I’ve been disappointed so often——”
He shook his head, his face sobering instantly. “I’m sorry to say I haven’t,” he answered; “I’ve done my best, too. But there, give the pledge, man. It’s little enough to give and I know you’ll keep it.”
“Very well,” I said at last, “I’ll keep secret anything you tell me, provided—well, you understand. I’ll give you my word on that.”
He sat up, smiling again. “Good, I took you for a man of sense and I was right. The suggestion I have to make to you is, that if you allied yourself with a certain organization, you would be in a better position to pursue your search. The organization can help you in many ways, and your search itself will be of help to the others—the men affiliated with you.”
“And the organization?” I demanded.
“The organization is the Secret Service of the United States!” he answered quietly.
I sat and stared at him at this. And the longer I stared the more indignant I grew. The thing was preposterous on the face of it. In the first place, what had he to do with the detection of crime—this fastidious young fop? Secondly, how could I pursue my own search if I joined such an organization, presuming for a moment that I could do so? And lastly, how could my search be of any possible benefit to the United States? Still he seemed sane enough. There was an earnestness about him that bade me hesitate in my indignation even. And he must have some object in his proposal.
